In the 1970s the solderless breadboard (AKA plugboard, a terminal array board) became available and nowadays the term breadboard is commonly used to refer to these.Breadboard is also a synonym for  prototype .Because the solderless breadboard does not require soldering, it is reusable. This makes it easy to use for creating temporary prototypes and experimenting with circuit design.n the 1970s the solderless breadboard (AKA plugboard, a terminal array board) became available and nowadays the term breadboard is commonly used to refer to these.
To make bread, find a wheat field and pick some wheat. Then find a windmill, and use the wheat in the very top floor of the windmill, putting it in the hopper, and then operating the hopper controls to send it down the chute. Then head down to the first floor and use a pot on the flour bin to acquire a pot of flour. Once you have your flour, use a bucket or jug of water with the flour to create bread dough. Then use the bread dough on a range to get a loaf of bread, which can then be consumed to heal 200 life points. Fires do not work for cooking bread. Using a jug or bucket of water on the bread will turn it into soggy bread.
